To all =1 ehmn. 1' t may moi warn;

. Beit known that I, Cnmnms TI. ELY, a. citizen of the United States,resident of East Orange. county of Essex, State'nf'New Jer- Sey, have.invented a eerlain new and useful lnnn-nvement in 'luoth- Brushes, atwhich the folluwing'is n speciliizaiiuu.

This invention relates to inniru'vemimts in -einlmil \'ing theiurentlun, and adapted 'to cleanse one ruw nl' teeth. and the cuttingedges therenf. I

Fig. 6 illustrates a modification employing' two sets of auxiliarybristles 8". 8". on opposite sides of the handle 3. By this deviceopposite cutting edges' of the teeth may be simultaneously cleaned.

Figs. 7 and 8 illustrate a detail of construction whereby the bristles 8are embedded in an inset plate 9. This plate may be held in place by anysuitable means, but

a certain amount of separation when the brush is in use.

The disks 1, 1, 1", 1 and 1 are provided with eountersinks for thereception of the headed ends of the shaft.

The operation of my improved brush is as follows:

The brush is placed within the mouth with a disk on cach'side of the rowof teeth to be "cleaned. On account of the arch in the disks reached.

the bristles on the lower sides of the will reach to the gums so thatthe entire exposed surfaces of the teeth will be The bristles on onedisk will engage the front of the teeth, those on the opposite disk willengage the rear and the lJIlSblfiS Oll the handle will engage the top01" crofin of the teeth The disks are so spaced that the hristles wil]nearly meet and will therefore reach well into the spaces between thetooth. The brush a now moved back and forth in the horixo tal directionand the engagement of 'the bristles on the disks with the tooth willcause the disks to rotate and this rotary movement will cause thcbristles on that side of the disks which axle " are moving toward thetops of the teeth not only to dislodge any substance which may bebetween the teeth but to actually carry it out of the space. Thefrohta'nd back of thc truth will be brushed with the proper rotarymovement and the crowns. or top will Insirnull'iinconsly brusinal.

- tendin" Having now described my invention, what I claim as new anddesire to secure by Let tors Patent, is:

1. A tooth brush having a handle, a bent axle carried thereby adjacentto one end thereof, a fixed brushing device carried b the handleadjacent to the axle, and a disc mounted on' the axle on each side ofthe handle, each disk having brushing devices on opposing faces.

2. A tooth brush having a handle, an axle carried b the handle, a (118kcarried on each end of tile axle and arranged one on each side of thehandle, a series of bristles carried by the handle, and series ofbristles carried by the disks on opposed faces thereof.

3. A tooth brush having a. handle, bristles carried by the handle, anaxle carried by one end of the handle and extending transversely theretoand to both sides thereof, a disk rotatably mounted on each end of theaxle, and a series of bristles carried by each disk, said bristlesextending toward the handle.

4. A tooth brush having a handle, a series of bristles carried by thehandle, an axle carried by one end of the handle and extran sverselthereto and to both sides thereof, a disk rotatably mounted on each endof. the axle, and a series of bristles carried by each disk, saidbristles extendin toward the handle and surrounding the first mentionedseries of. bristles.

5. .11 tooth brush having carriedby the handle, said axle having a bentportion, a disk mounted on each side of thebent portion, each disk beingcapable of independent rotation, a series of bristles carried on opposedfaces of the disks, and a series of bristles supported intermediate thedisks.

6. A tooth brush, having a handle, a shaft carried thereby, two diskscarried by said shaft one on eaclrside of carried by said disks onopposing faces thereof, and yielding means for holding said disks inposition to engage the bristles with a handle, an axle the sides of theteeth.

7. A-tooth b'rush havin a handle, a shaft carried thereby, two dislzscarried by said shaft and arranged one on each side of the handle, aninset plate carried by said handle, bristles carried by said insetplate, said plate being of less thickness than the handle, and bristlescarried by said disks on opposing 'l'nrrs thereof.
